Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] In an embodiment of the present invention, various images are displayed by a display instead of a light source or a color palette. The camera is positioned at a relatively fixed position relative to the display through the fixture, and the camera shoots images displayed on the display under the positioning of the fixture. A device for detecting shooting performance, such as a main control computer or a PC, detects the performance of the camera by analyzing the image quality captured by the camera. Automate camera detection. The monitor, the fixture, and the camera are in the same dark box, that is to say, the camera shoots the image displayed on the liquid crystal display in the dark box, avoiding the influence of external light on the test process and the...

Abstract

This invention discloses a test system and a method for camera heads to realize automatization, in which, a display displays images, a camera head to be tested shoots images displayed by a display localized by a clamp, then a device for testing performance of shooting, such as CPU or PC is used to analyze the quality of the image shot by the camera head to test the performance of the head, and the display can be a LCD, and the LCD, the clamp and the camera head are in a same camera.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to detection technology of electronic equipment. Background technique [0002] With the rapid development and popularization of communication technology, the services provided by mobile phones have increasingly changed people's lives and work, enabling people to exchange information anytime, anywhere, in a timely and reliable manner, without time and space constraints, and improve their work. efficiency and economic benefits. Therefore, the population of mobile phone users is growing rapidly. Taking my country as an example, from 2000 to 2002, the number of mobile phone users increased by 41.97 million, 59.55 million and 61.39 million respectively. In 2003, the number of mobile phone users reached 62.7 million. By the end of October 2003, my country's mobile phone users had reached 256.938 million, surpassing fixed phone users for the first time in history. [0003] At the same ...
